The LH exhibits input bias currents typically. The LH is a 2 stage amplifier with a high. National Semiconductor Electronic Components Datasheet. National Semiconductor Electronic Components Datasheet. Operational amplifier, A” receives. For the LH, equation 4 reduces to: Figure 11 is a plot of bandwidth versus RB.
In the standard configuration, pin 1 of datashdet LH An internal factory trimmed resistor, R6, will. Should a higher CMRR be desired, pin 9 should be left open and the procedure, in this section followed. The implication is that a finite impedance must be supplied between the input and power supply ground.
Equation 5a re-arranged in more convenient form may be used to select RG for a desired gain: The source impedance looking into pin 2 is approximately 15 kD. LlW 10k k 1. Guard Pin With Buffer. Should a higher CMRR be desired, pin 9 should. In applications in which the signal source is float. The amplifier’s slew rate in this configuration is typically O. It also should be noted that large signal bandwidth. For applications requiring a lower source impedance. In some applications, particularly at low frequency, it may be desirable to limit bandwidth in order to mini- mize the overall noise bandwidth of the device.
Common Mode Range 10V for. Pin 2 of the LH is provided as a guard drive. G 4 As can be seen for identically matched resistors, eCM is cancelled out, and the differential gain is dictated by equation 4. A resistor Raw may be placed between pin 1 and ground to accomplish this purpose. Pin 2 will always be biased at the input common. Pin 2 will always be biased at the input common mode voltage.
Pin 9 should be grounded for nominal operation.
Under worst case conditions: Bias Current Return Path. This current must flow through Rise as shown in Figure The amplifier’s slew rate in. Off-set may be nulled using the circuit shown in. The value of the resistor is dictated by. Rise causing a voltage rise at point A. The source impedance looking into. LH may be inserted between pin 2 and the. Bandwidth vs Raw It also should be noted that large signal bandwidth and slew rate may be adjusted down by use of Raw.
Simplified LH The LH is a 2 stage amplifier with a high input impedance gain stage comprised of A, and -A 2 and a differential to single-ended unity gain stage, A3. Figure 2 shows typical small signal bandwidth versus R BW. As can be seen for lh003 matched resistors.

Proper use of the. The implication is that a finite impedance must. The value of the datashheet is dictated by the maximum input bias current, and the common mode voltage. Use of Guard For applications requiring a lower source impedance than 15′ kD, a unity gain buffer, such as the LH may be inserted between pin 2 and the input shields as shown in Figure Figure 11 is a.
Pin 8 is also used to improve the common mode.
